Passive Infra Red (PIR) motion detector module measuring just 35x25x16mm as used in commercially made alarm systems. It can be used for detecting the presence of people, animals and other moving heat sources. Detection range is up to 8 metres.

Requires only three connections: V+, GND and OUT. Supply voltage may be from 4-12Vdc (see Order Code 3133 for a 10-14Vdc, active low version of this product).

The output is a TTL active high going pulse with a minimum duration of 0.5 seconds that remains active as long as motion is detected. The output can be directly connected to a microcontroller, logic device or used to switch an external load via a relay, triac or opto-coupler. The low impedance (under 35 Ohm) enables it to directly drive a small 100 Ohm relay through a 150uF series capacitor.

The modules main components are a PCB mounted Fresnel lens, an RE200B PIR sensor and a custom-made, surface mount movement detector IC.

Dimensions: 25x35x16mm. Supply: 4-12Vdc (use a regulated supply like out PSU443 with connector 7-1012). Operating current: 400uA at 5V. Power up delay: 25 seconds. 4 fixing holes at 19x30mm centres)
